In the "Chart" sheet of the spreadsheet, there is a chart which represents the number of days between encashment and PER. Unfortunately, there is a huge amount of standard deviation from 10th October to 25th October (roughly speaking). the processing time for encashment was 2 months for that interval. It's just a guess, and I am NOT sure: It means that something has happen in the last three weeks of December.
For example, defining a new task for the staff, the New Year, or moving the documents or applications from one building to an other (I AM NOT SURE, JUST A GUESS). When a movement happens, possibly some applications are ordered disorderly! (Human error). We don't know whether they have assigned a number to an application just at the time of receiving. If they assign a number to each application immediately, they can trace it internally, and there is no reason for any kind of problem (such as incorrect arrangements in a queue)
Another hypothesis is that a selective process is in progress. In my opinion, it's impossible because they have announced that the defined process is a First Input First Output (FIFO) process, and they are considering the files according to the date of arrival.
Another hypothesis is that 25000 cap has been reached (in overal), and they stop working on NOC 4011. This contradicts with statistical data in the spreadsheet. Nevertheless, the spreadsheet is not accurate.
One of our friends (in this topic) said that they were told to wait till March 3. Perhaps a new version of a piece of software or data bank will be implemented till then, and some random NOCs have been selected for being used as a pilot plan.
Another solution: they are going to program a nine-month process for the rest of applications. This may be visible in the first rows of the spreadsheet. Therefore, some modifications in the most crowded NOCs is required.
Important note: all of the above-mentioned hypotheses are just some fictitious solutions to a real problem. Just the time will derive the exact solution; nevertheless, it is very hard to be patient...
